Orbitron atomic orbitalsThis is to announce the first draft of The Orbitron - a web site with ray-traced images representing atomic orbitals. The site also has some animations that should help you to visualise them

The site shows images representing electron density and animated plots that should help you to understand their nodal structures. Future versions will have molecular orbitals as well. The images are "ray-traced" which hopefully means pretty (as well as informative).
